The haircut was the culmination of the Veterans of Foreign Wars' seven-week Mane Event to raise awareness for veterans issues.

"I understand the issues that veterans and their families face while serving our country, and I am honored to join the Veterans of Foreign Wars Mane Event, encouraging the nation to unite for veterans for a second year,” said Polamalu. “By getting my hair cut on Veterans Day, I am showing my commitment to the men and women who served our country, the real heroes."

According to Chris Strauss of USA Today, it was Polamalu's first haircut in 11 years, and he'll be auctioning off his hair to support the foundation.

I'm not sure why anyone would want to purchase someone else's hair as a memento, but to each their own, right?

Besides, anything that raises awareness for our veterans and the many sacrifices they have made for the rest of us is an excellent and worthwhile gesture.

It got me thinking, though. What other famous attributes of well-known athletes could be auctioned off?

These are a few that I came up with off the top of my head. Be sure to leave more in the comments!

Obviously, Polamalu cut a few locks because it was a nice thing to do, not because it would bring him some good karma, but man alive, the Pittsburgh Steelers could really use some good karma.

The team is currently 3-6 and is in danger of not having a winning record for the second season in a row. Ben Roethlisberger trade rumors have surfaced—though he's shot them down in no uncertain terms—and a proud, normally physical defense is currently 29th in run defense.

So, yeah, the Steelers could use a bit of karma.

For years, Polamalu's hair flopping about underneath his helmet normally meant a big play from the safety was about to happen. Now, the Steelers would probably be willing to go the superstitious route and hope his locks bring them some good vibes, too.
